im on 15 lbs on my s15 turbo on s14 blacktop how will 630cc injectors run on it?

What tune? Fuel management?

If you're asking if you can just stick larger injectors on the car, no. If you have have something to tune with they'll work just as good as any other injector upgrade. It's not like 630cc is a magic or weird number.

what about 550cc i still needa tune?

Yes. How do you think the ECU will recognize the bigger injectors? You have to do something to alter the signal, otherwise the ECU will still be looking at the stock 480s, no matter what.

Go read up on injector sizing and tuning before you go any further.

The size that you put in I guess. I don't know your car, your parts, plans, goals, or anything.

But I'm done. Your questions have been answered. Research more, it's obvious you're unsure about what you're about to get into.

Well 550's will work 630's will work the stock ones will work too. You need to tune appropriately for the amount of boost you are planning on. I'd personally go higher with the 630's to give you some room to work with down the road.
